Sonic Union Adds Mix Engineer Julienne Guffain

NYC-based creative audio studio Sonic Union announces the addition of Sound Designer/Mix Engineer Julienne Guffain. Working across Sonic Union’s Bryant Park and Union Square locations, Julienne brings over a decade of experience in audio post production and a vivacious energy to the team. Having worked on top television, film and branded projects for clients such as Google, Mountain Dew, American Express and Cadillac among others, she’s anxious to expand her reach.

“A decade ago, I became aware of Julienne’s talents and was suitably impressed. From that moment, she was on the radar as an up and coming creative engineer to keep an eye on,” says Co-Founder Steve Rosen. “It’s really evident how much people enjoy being around Julienne, and the passion that she brings into each project”.

A Virginia native, Julienne followed her film aspirations to NYC to attend New York University’s prestigious Tisch School of the Arts. Finding herself drawn to sound in film, it was at NYU where she cut her teeth as a foley-phile and mixer on student films and independent projects. She landed her first industry gig at Hobo Audio, earning mix credits for top clients such as The History Channel, The Discovery Channel, and mixing the powerful Emmy-winning television documentary series “Rising: Rebuilding Ground Zero.” Making her way to Crew Cuts, she began lending her talents to a wide range of spot and brand projects, including the documentary feature "Public Figure," which examines the psychological effects of constant social media use. It is slated for a festival run later this year.

“I’ve always admired Sonic Union from afar, their reputation for quality work precedes them, and the vibe of the place always appealed to me" said Julienne. “I’m thrilled at the opportunity to work and hang alongside this talented team, and continue to broaden my abilities”.
